RAIL ANCHOR.

Application filed April 27, 1923. Serial'N'o. 273375.

Our invention. relates to rail anchors, and

. com arises certain improvements in the tv 3e of anchorswhich are mounted in clamping engagement with the 'haseflanges of a rail and cooperate with the ties to prevent creeping of the rail.

An important object of our invention is to provide an anchor having walls in positive engagement with the edge ofeach'haise flange of a rail.

A further object of our invention is to provide an anchor made up of a series of curved webs or walls avoiding sharp angles; such curved portions permittin 'e'ht llGXHl'G to insure clamping engagement with the base flanges of a rail upon the insertion of a key between a portion of the anchor and the base of the rail.

And a still further object of our invention is to provide a portion of the webof the anchor with a slight concavity to serve as. a

guide for the key.

These and other features of our invention are more fullyv described hereinafter; ref

erence being had to the accompanying drawings, in which: a

Figure l is a cross-sectional view of a conventional rail showing our improved rail anchor in position for application thereto; different positions assumed during application being indicated.

Fig. 2 is a similar view, showing the anchor in operative position with respect to the base flanges of a rail; the fulllines showing the position before, and the broken lines the position after, the insertion of the key.

Fig. Sis a similar View, showing the anchor in clamped position, with a locking key interposed between a portion of the same and I The ends of our improved anchor are provided with overhanging lips or flanges 1 and 2, adapted to overlie the edges a med a of the respective base flanges of a rail A, when in the operative position, as clearly indicated in Figs. 2 and 3. Below these flanges,"short walls 3 and 4, substantially vertical, are provided, fromwhich extend the curved portions 5 and 6, connected to a portioni7, substantially'central-ly disposed with respect to said portions 5 and 6. The portion? maybe disposed .in 'asubstantially horizontal-plane which may be parallel to the underside of the rail base, and this is the position when the key is in place, as indicated in Fig. 3. Preferably, the

upper surface of the 'portion7 is slightly inclined, as indicated-by the full line'posit-ion, Fig. 2. The curved portion 5 at What may he termed the front of the anchor comes forwardly so as to give sufficient space permit ting application to the rail; the relatively long. wall permitting flexure. The curved w l 6 also extends in the same general direction and'it-s relation to the wall 4 is such as to provide a seat 4 for the edge a of the base flange between such curved portion 6 and the substantially vertical portion 4.

The anchoris held in clamping position with'respect to the base'ilanges of the rail A by the applicationof a key 8, which maybe passedt'hrough an aperture 9 formed in the curved wall portion 5 ofthe anchor; such key being forced to its seatbetween the portion 7 of the anchor and the underside'of the rail base. This action flexes the walls of the anchor and sets up suiflcient tension to hold the key in place and maintain the'anchor in clamping position with respect to the base flanges of the rail. p I

By preference, the flange or lip 1 has line engagement with the base flange a, as indicated atm, and the flange or lip 2 may be similarly arranged if desired. The portion 7,

between the curved portions 5 and 6, may be hollowed out slightly, as indicated at 7 in Figs. 4: and 4 to serve as guiding means for the key when the latter is introduced for the purpose of clamping the anchor to the rail. An ordinary railroad spike may be employed as the key. 7

By having the walls 3 and 4 of the anchor in engagement with edges of the base flanges and with a seat such as indicated at i for one of said flanges, that indicated at a, between the lip 2 and the curved portion 6, the anchor is prevented from displacement; there being no opportunity for endwise movement after the key has been finally seated.

We claim:

1. A rail anchor comprising a body of resilient metal extending transversely of a rail beneath the same and adapted to embrace the langes thereof; said anchor having substantially vertical end walls arranged for engagement with the edges of said rail flanges and curved portions continuous with said en d walls and joining a substantially straight intermediate portion below said base flanges; one of said curved portions having an aperture below an end Wall for the insertion of a key between the bottom surface of the rail base and the upper surface of the intermediate portion of said anchor to flex the,

body of said anchor into clamping ment with the base flanges of a rail.

2. A rail anchor comprising a body of resilient metal extending transversely of a rail beneath the same and adapted to embrace the flanges thereof; said anchor having sub stantially vertical end walls arranged for engagement with the edges of said rail flanges and curved portions continuous with said end walls and joining a substantially strai ht and slightly inclined intermediate portion below said base flanges; one of said curved portions having an aperture below an end wall for the insertion of a key between the bottom surface of the rail base and the upper surface of the intermediate portion of said chor to flex the body of said anchor into clamping engagement with the base flanges of a rail.

3. A rail anchor comprising a resilient member adapted to embrace the base flanges of a rail and having a pair of inwardly turned lips at its ends, a vertical portion adjacent each of said lips, curved portions continuous with and extending from said vertical portions toward each. other and joining an intermediate straight portion disposed above the plane of the lowermost parts of said curved portions and extending transversely of the rail; one of said vertical walls being apertured for the insertion of a key be tween the bottom of the rail base and said intermediate portion to flex the anchor into clamping engagement with a rail base.

4. A rail anchor comprising a resilient member adapted to embrace the base flanges of a rail having a pair of inwardly turned lips at its ends, a vertical portion adjacent each of said lips, curved portions continuous with and extending from said vertical portions toward each other and joining an in termediate straight portion disposed above the plane of the lowermost parts of said curved portions and extending transversely of the rail; one of said vertical wallsjoining the curved wall in such manner as to provide a seat for the edge of one of the base flanges and the other curved wall being apertured for the insertion of akeybotween the bottom of the rail base and said intermediate portion to flex the anchor into clamp ing engagement with a rail base.

5. A. rail anchor comprising a resilient. member having inwardly turned terminal lips joined by an intermediate section made up of vertical-walled sections adjacent said lips, curved sections, and a section substantially straight underlying the base of the rail; said curved sections being adapted to flex under the pressure exerted bya key driven transversely of the rail between-the bottom thereof and the intermediate portion of the anchor and said intermediate portion being slightly grooved to guide the key. r

6. A rail anchor comprising a resilient member having terminals with substantially vertical walls and inturnedlips or flanges adapted to overlie the base flanges of a rail and a connecting-portion for said end walls comprising curved portions connected by a substantially straight web portion underlying the base of the rail, in combination with a key adapted to be driven transversely of the rail 1 etween the bottom thereof and the web portion underlying the rail base; said web portion being substantially horizontal and parallel with the underside of the rail base when the key is in position. i

In witness whereof we have signed this specification.
